Two new projects have been revealed on the Paradox forums, here and here.

The codenames for the projects are Nero and Armstrong respectively.

Nero could mean a new Rome game and Armstrong possibly some sort of space colonization game - considering the Cold War is already taken. If that is indeed the case I expect Armstrong to be a case study, similar to Sengoku, since 1) not sure the team can handle two projects at the same time and 2) it would be a whole new setting for them. Both are likely to be Grand Strategies.

The full project details will be revealed on the 23rd of January 2014. Tacticular cancer will keep up to date on any developments.
